Original application filed February 26, 1925, Serial No. 11,6651. Dvdedand thisapplieaton led June 23, 192,5. Serial No. 39,070.

i. 10 all whom t may concern.'

Be it known that I, FRANKLIN R. VHrin, a citizen of the United States of America, residing at Waterbury, in the county of New Haven andState of Connecticut, have invented certain new and useful improvements in Button-Attaching Machines, of which the followingl is a specification.

My invention relates to new and useful improvements in button attaching` machines and more particularly to the means for receiving the button from the button chute and supporting the same `as it is carriedto the anvil to be attached bythe action of the plunger.

The present application is a division of an application filed by me on February 26,1925, bearing Serial Number 11,664, the above application being drawn to that part of the machine which feeds and delivers thetacks to the anvil.

The present application, also, is an 1mprovement on the `button receiving means as shown in the patent granted to me on December 2, 1913, No. 1,079,968. As may be seen in that patent, in 9 especially, a pair of jaws is provided at the end of an arm, which aws are cup-shaped at their outer ends and receive the buttons `as they nass from the button chute. These jaws lower withthe plunger until the button is just above the cloth, after which the plunger forces the button still further downwardly, driving in the tack positioned on the anvil.

In years of actual service of the machine, as set forth in the Patent No. 1,079,968, I have found at different times that the button after it leaves the escapeinent in the button chute, will pass down the chute into the button receiving member and due to its speed, the button will at times jump or fly from without the cup-shaped receiving jaws, so that when the plunger descends, the button head is missing.

In a patent granted to me on October 26, 1915, No. 1,157,743, there is shown an escapement for the buttons which is automatically operated but which `may also be manually operated, and in the past when a button jumped from the button receiving jaws the escapement was manually operated to thus .feed another button to the cup-receiving jaws.

Desiring, therefore, to speed up the work and to prevent the fed buttons from leaving the chup-receiying jaws until attached, I have provided a similar set of cup-receiving jaws with the addition, however, of a superimposed set of jaws, so that when the button leaves the chute and slides within the main button receiving jaws, the superimposed jaws will act as a Vtop wall and prevent the buttons from jumping from without the main jaws. Y

Still another object ofthe invention is'to provide a button receiving means comprising two sets of pivotal jaws, the lower pair of which is cup-shaped at their outer end, to

although a pair of superimposed jaws is provided to retain the button within the button receiving means, they in no way interfere with the stroke of the plunger as they are so constructed as to be spread and forced 'out of the way as the plunger "starts its downward stroke.

Still another object of the invention is to provide a button receiving means which may bequickly assembled, relatively cheap to manufacture and. may be easily manually opened, if for any reason a defective button should be fed to the button receivingjaws.

With these and other objects in view, the invention consists in certain new and novel constructions and combination of parts` as will be hereinafter more fully described and pointed out in the drawings. j

VReferring now to the drawings showing a preferred embodiment of my invention, 'l Fig. 1 is a fragmentary side elevation of a button attaching machine, the improved button receiving means being shown in their normal position. ,Y

Fig. 2 isa similar view showing the button receiving means being forced downwardu ly by the plunger to place the button di`v rectly above the tack.

Fig. 3 is a top plan view of thebutton receiving means showing the supplemental jaws in their normal position.l

Fig. el is a detailed sectional view ot the jaws and plunger' in the position shown in Fig. 5 is a tcp plan view showing the sup" pleinental jaws spread by the action of the plunger.

Fig. 6 is a detailed sectional view ot the same.

'l' is a top plan showing both sets oi" jaws in their spread condition.

Fig. 8 is a det-ail section ot the saine.

Fig. 9 is a view of the button receivingj inernber vwith the supplemental jaws removed, and

Fig. v10 is `a view ofthe button receiving arin with Aboth 4sets of jaws removed. l

Referring'now to Fig. 1, there is shown a fragmentary portionot a standard 1, provided Awith the bearing `2 'for the rreception of the plunger V3 together with .the button receiving arin 4. A fragmentary portion of a tucker slide 5 is shown-as well as a portion of a means 6101' manually operating the saine, all ot which parts are `.fully described in my eo-pendinrapplication, bearing Serial No. 11,6641. 1

An anvil 7 and the tack receiving :jaws maybe noticed at the base ot the lstandard 1, but this portion ot the device forins no part'vot the present invention, this being shown in `the patent granted to nie on lune 17, 1924, No. 1,497,818.

Still referring to Figs. 1 and there may be seen-a fragmentary portion of a button delievery Chute 9, which extends troni a hop per (not shown) directly beneath the plunger 3, 'the position of the -chute being 4such that the plunger niay pass through the biurcated end of the saine.

The arm fl is pivoted as .at 10 within the standard and comprises the vertical Vpart 11 from which extends lthe horizontal portion 1Q, land then 'the portion 13, in the forni ot an arm, extends downwardly 'towards the plunger, as may `be clearly seen inthe several views.

Mounted on this portion 13 as inay he seen 'from Fig. 10, yis a small lifting member 14 pivotally held by the pin 15. The portion 13 of the arm is'slotted at its` end as at 16 and extending upwardly is the small spacer lug 17, while rin alignment therewith and above the saine, is Vthe small post 18 with the integral cap V19 formed thereon.

Referring now preferably to Fig. .9, lthere 'will be noticed that pivotally mounted on the portion 13 are the split :jaws 20, their inner ends being semi-circular as at 21 to encircle the post 18 and it under the cap 19, these jaws being held shut by the provision ott a sinallvspring 22 which encircles the upper end of the jaws and has its ends litting within the little' apertures 23 in the jaw pieces as is :the usual practice.

The outer ends of the jaws 20 are cupped vspeciti "ation, that Figs. 3V to 9 inclusive, show the button receiving ineans and the plunger as well as the position 01' the several parts during the opera-tion ot the jaws when the .plunger descends, and `tor the salie ot clearness of illustration, the button has been omitted from the pocket, but it will be appreciated that when the button is lodged within the .inain jaws, vthe plunger when assuming the positionshown in Figs. 5 to 9 will impinge'against the 'button head and the side walls `or .perimeter ol the button will Contact with the lower 4jaws to `torce theni apart, rather thanthe end of the plunger.

rlhe shape of these inain jaws 2U and their` construction is very similar to that shown in my Patent No. 1,079,968, small guide walls however., areshown in the present 'l'orin which aredesigned to guide the button as it leaves the chute 9 directly into the pocket at 'the end of the jaws, The jaws 9.0 are each provided with a threaded opening 2C for the `reception ot screws 2i whieh in turn are passed through the ends 28 ot the two further jaw pieces 29 which are superimposed upon the jaws Q0 yas may be seen lin the several `figures.

Small holes 50 are provided in the sides ot these jaws tor the reception ot the ends of the spring 31 which spring tends to keep these jaws normally closed as will be readily understood.

These jaws 29 are provided on their oner ends with the lips 29, the position and width of the. jaws .being such that the lips lie directly7 in the path of the plunger 3 as niay he seen in lthc several figures. VThe right hand piece ot the jaws 29 is curved slightly outwardly at its upper end. as may Le seen in Figs. `3, ll `and 7, so that the saine may be easily grasped by the operator it desired to open the jaws to remove any detective button.

The lips 29 of the jaws 29 lie directly above lthe pocket 24 or cup-shaped portion of the Vlower jaw and it will be readily unF derstood that when a button passes down the chute. 9, and drops into the cup-shaped portion and rests on the lips 245, of the lower jaws, it will he prevented troni jarring or flying out ot its pocket as the lips 29 'torni a substantial upper ledge or cover 'tor the pocket.

Referring again for the 1 und 2, as to `the button receiving' arm it will be noticed that its upper and lower limits of movement are regulated by the upper set screw 32 and a similar lower one 33, the upper screw inipinging against a portion Sel ot the standard 1, and the lower one against a spring-pressed pin 35,Y the inoinent to Figs.

i: iously mentioned patent.

spring (not shown) being encased within the housing l i I rlhe operation is as follows z-Presuming that a button has passed down the chute 9 and rests within the cup-shaped portion of the lower jaw 20, the plunger', in its regular cycle ot operation will move downwardly and assume the position shown fragmentarily in F ig. Ll. The lower' end et the plunger presses against the slanting walls ot the lips 29 of the jaws 29 and forces them apart as shown in Fig. G. The plunger now impinges against the top the button (not shown) and as the plunger descends it moves the arm fl downwardly and forces the button against the lips 2d" and spreads open these lower jaws, and the tack on the anvil will be forced through the material and up into the button head. Y

The lifting member 14 on the upward stroke of the plunger and the. rise of the arm Li, will lift the button and Clo-th `upwardly, after which the cloth will be pulled outwardly and moved for the next button.

It will be 'understood that as the plunger descends, the arm el and the awsV will move downwardly by the action ot the plunger, this action being the same. as in my prev- 'Ihe advantages of the present construction will ybe readily appreciated, as it is impossible for a button to speed down the chute into the lower jaws andtly therefrom as the supplemental jaws provide an upper wall, substantially closing the cup-shaped pocket. The supplemental jaws in no way act as a detriment as the plunger easily spreads them as it contacts with their lips. The supplemental jaws are normally closed and are only opened when the plunger spreads them.

From the foregoing it will be seen that I have provided a button receiving means comprising a main set of jaws, which are cupped at their outer end to receive the descending button and that I have provided a supplemental pair of jaws which are superimposed and restrict the button Jfrom any outward movement.

Many slight changes might be made without in any way departing from the spirit and scope of the invention.
